TECHNICAL FIELD

The present invention relates to an awning support device, and more particularly, to an awning support device that enables an awning to be easily set up and dismantled at any time and in any place and can stably support the awning.

BACKGROUND ART

A general awning device refers to a device that is installed on an exterior wall such as a doorway or a window of a building to block sunlight by an awning or sunshade, thereby preventing sunlight from entering the building.

Although the awning device is mainly installed and used on the exterior wall of the building, it is recently installed and used not only on a camping car for enjoying camping but also on a roof of a van or a passenger car.

In order to quickly and conveniently set up an awning for securing shade during camping, an awning device is installed on a roof of a vehicle to provide shade around the vehicle.

An awning device for a vehicle of the related art includes a frame fixed to a roof of a vehicle or a roof rack provided on the roof, an awning wound inside the frame, and a vertical pole installed at an end of the awning to support the awning spaced apart from the ground.

The frame of the awning device for a vehicle of the related art has a considerably long length and is heavy as an awning with a relatively large width is set up in order to secure a shade space as wide as possible. Above all, the awning device is installed protruding outward from the vehicle, so the overall appearance is poor.

In addition, the awning device for a vehicle of the related art has a problem in that only a dedicated awning wound in the frame can be used because the awning is connected to the frame.

DETAILED DESCRIPTION

Hereinafter, an awning support device according to preferred exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 1 and 2 show an awning support device according to an exemplary embodiment of the present invention. Referring to FIGS. 1 and 2 , an awning support device 1 according to an exemplary embodiment of the present invention includes a vertical support unit 100 and a horizontal support unit 200.

The vertical support unit 100 may be configured as a pair.

The vertical support unit 100 includes a vertical pole 110 and a plurality of extension poles 120.

The vertical pole 110 has a circular hollow pipe structure having a certain thickness so as to be erected on the ground or installation target surface.

The extension pole 120 is a pole connected to a lower part of the vertical pole 110 so as to position the vertical pole 110 at a desired height from the ground or installation target surface, is formed to fit an upper end thereof into a lower end of the vertical pole 110, and is also formed to be mutually fitted and coupled in a vertical direction. As the extension pole 120, a pole that is used for a normal tent or tarp may be applied.

The vertical pole 110 and the extension pole 120 can be configured in a plugging manner like a fishing rod, thereby extending or reducing a length.

Although not shown in the drawings, the vertical pole 110 may be rotatably coupled at a lower end to a rotary bracket installed on the floor of a trunk or loading box of a vehicle so that the vertical pole 110 can be laid down parallel to the floor of the trunk or loading box of the vehicle or erected from the floor. In this case, the rotary bracket and the vertical pole 110 may be installed in a drawing-in groove drawn downward in the floor of the loading box or trunk, and accordingly, it is preferable to ensure that no interference occurs when folding the vertical pole 110 toward the floor and when loading cargo or objects in the loading box or trunk. The vertical pole 110 can be rotated up and down by the rotary bracket, and a fixing structure can be applied in order to continuously maintain an erected state in the erected state. For example, the vertical pole 110 may be fixed in an erected state by using a pin member fastened through the rotary bracket and the vertical pole 110.

The horizontal support unit 200 is a unit installed on the vertical support unit 100, is installed by at least one on the vertical pole 110, and extends away from the vertical pole 110 to support an awning 5 from below so that the awning 5 does not sag down. Although only one horizontal support unit 200 may be installed on the vertical pole 110, a plurality of horizontal support units 200 may also be installed on the vertical pole 110, as shown in FIG. 3 . When installing the plurality of horizontal support units 200 on the vertical pole 110, the horizontal support units 200 may be installed in a manner of being vertically stacked along a longitudinal direction of the vertical pole 110.

More specifically, the horizontal support unit 200 may include at least one main holder 210 and a support bar 250.

The main holder 210 is installed to surround the vertical pole 110 and to be rotatable along the vertical pole 110, and a plurality of main holders may be arranged along the longitudinal direction of the vertical pole 110, as needed. The main holder 210 may have an inner diameter slightly larger than a diameter of the vertical pole 110 such that the vertical pole 110 can be fitted therein. One side of the main holder 210 is formed with a mounting protrusion protruding outward such that the support bar 250 can be inserted and coupled thereto. The mounting protrusion is formed with an insertion hole into which the support bar 250 is inserted and coupled.

Unlike the illustration, the main holder 210 may be omitted, and when a diameter of the support bar 250 is large enough to allow the vertical pole 110 to pass through the support bar 250, the support bar 250 may be directly rotatably installed on the pole 110.

One end of the support bar 250 is coupled to the main holder 210, and the other end extends radially away from the main holder 210. As shown, the support bar 250 may have a detachable structure with respect to the main holder 210 such that it can be fitted into or separated from the mounting protrusion provided on one side of the main holder 210, but the support bar 250 may also have such a structure that the support bar is formed integrally with the main holder 210. When a detachable structure is applied so that the support bar 250 can be fitted into or separated from the main holder 210, a user can select and install a plurality of support bars 250 having different lengths or thicknesses, as needed.

A damage prevention cap 260 made of rubber or silicon may be further provided at an end of the support bar 250 so as to reduce damage and breakage to the awning 5. The damage prevention cap 260 may be integrally formed at the end of the support bar 250, but the support bar 250 and the damage prevention cap 260 may be separately configured, and a hole may be formed on one side of the damage prevention cap 260 so that the support bar 250 can be fitted therein.

The support bar 250 may be formed of a hard plastic or metal material such that there occurs no flexing or bending, or may be formed to have elasticity or to be flexible such that it can be bent or flexed in all directions. The support bar 250 as described above supports the awning 5 upward at a lower part of the awning 5 such that the awning 5 does not sag down, and therefore, the awning 5 does not sag down or flutter. As a result, a space under the awning 5 can be made wider and used without interference of the awning.

The main holder 210 is formed to make it possible to rotate the support bar 250 along the circumferential direction of the vertical pole 110. The main holder 210 is formed to make it possible to fix a rotational position of the support bar 250 after rotating the support bar 250 to a desired position along the circumferential direction of the vertical pole 110.

More specifically, the main holder 210 may include an upper coupler 220 and a lower coupler 230.

The upper coupler 220 includes a body 221 and a compression rib 222.

The body 221 has a cylindrical shape with a through-hole in a center such that the vertical pole 110 can be fitted therein. An inner diameter of the through-hole may be formed slightly larger than the diameter of the vertical pole 110 such that the body can be moved up and down along the vertical pole 110. Alternatively, the inner diameter of the through-hole may be formed substantially equal to the diameter of the vertical pole 110 such that the body can be forcibly moved up and down along the vertical pole 110 by external force.

The compression rib 222 extends downward from a lower end of the body 221 for a predetermined length and has a structure such as a collet chuck in which it is divided into at least one or more pieces along the circumferential direction of the body 221. A threaded portion 223 is formed on an outer circumferential surface of the compression rib 222. The compression rib 222 has such a structure that an inner diameter can be gradually reduced when screwed with the lower coupler 230 described later. In addition, the compression rib may be formed to press the outer circumferential surface of the vertical pole 110 to some extent while an inner circumferential surface of the compression rib comes into close contact with the outer circumferential surface of the vertical pole 110, so as to prevent the body from sliding down along the vertical pole 110. To this end, the inner diameter of the compression rib may be formed slightly smaller than the outer diameter of the vertical pole 110.

The lower coupler 230 has a cylindrical shape with a through-hole in a center such that the vertical pole 110 can be fitted therein, and an inner circumferential surface of the through-hole is formed with a threaded portion 233 that is screwed with the threaded portion formed on the outer circumferential surface of the compression rib 222.

When screwing the compression rib 222 of the upper coupler 220 and the lower coupler 230, the inner circumferential surface of the compression rib 222 comes into strongly close contact with the outer circumference of the vertical pole 110 while the inner diameter of the compression rib 222 is reduced, thereby preventing the main holder 210 from moving up and down along the vertical pole 110, and making it possible to fix the main holder 210 at a certain height of the vertical pole 110.

Although not shown in the drawings, a close contact pad formed of rubber or silicon material is provided on the inner circumferential surface of the compression rib 222 to increase the adhesion and frictional force to the outer circumferential surface of the vertical pole 110, thereby increasing the fixing force of the main holder 210.

Meanwhile, the awning support device according to an exemplary embodiment of the present invention may further include a supporting unit 400.

The supporting unit 400 is coupled on one side to the vertical pole 110 side, and is coupled on the other side to an end side of the support bar 250 far from the vertical pole 110, thereby supporting the support bar 250 with respect to the vertical pole 110. The supporting unit 400 prevents the support bar 250 from being bent downward or upward due to external force applied to the support bar 250 from above or below the support bar 250.

FIGS. 4 and 5 show an exemplary embodiment of the supporting unit 400.

Referring to FIGS. 4 and 5 , the supporting unit 400 includes a lower auxiliary holder 410 installed on a lower side of the main holder 210 to support the support bar 250, and a lower support rod 420.

The lower auxiliary holder 410 is installed to surround the vertical pole 110 on a lower side of the main holder 210, and is formed on one side with a ball joint part 411 capable of supporting the lower support rod 420 (which will be described later) so as to be rotatable by certain angles in the vertical and horizontal directions. The lower auxiliary holder 410 and an upper auxiliary holder 430 described later may be installed to be rotatable about the vertical pole 110, respectively, or otherwise, may be fixed to be non-rotatable, and may be installed to be rotatable or fixed with respect to the vertical pole 110, as needed, by applying the structure of the upper coupler 220 and the lower coupler 230, like the main holder 210 described above. Unlike the illustration, the lower auxiliary holder 410 may be formed with a fitting hole capable of interference-fitting an end of the lower support rod 420, instead of the ball joint part 411.

The lower support rod 420 is coupled at a lower end to the ball joint part 411 provided for the lower auxiliary holder 410 so as to be rotatable by certain angles in the vertical and horizontal directions, and is rotatably coupled at an upper end to a connecting bracket 270 coupled to one side of the support bar 250. A spherical ball member 421 is provided at the lower end of the lower support rod 420 coupled to the lower auxiliary holder 410, and the ball member is coupled to the ball joint part 411 so as to be rotatable to some extent in the vertical and horizontal directions in a state of being restrained in the ball joint part 411. Unlike the illustration, when the lower auxiliary holder 410 is formed with the fitting hole, the lower support rod may be interference-fitted into the fitting hole.

The lower end of the lower support rod 420 is coupled to the lower auxiliary holder 410 below the main holder 210 and the upper end of the lower support rod 420 is coupled to the support bar 250, so that the supporting unit 400 can stably bear and support load acting on the support bar 250.

In addition, when the plurality of horizontal support units 200 are installed on the vertical pole 110 as shown in FIG. 6 , the supporting unit 400 may further include a plurality of lower support rods 420 for supporting the plurality of horizontal support units 200, and a lower auxiliary holder 410.

In order to allow the lower support rods 420 for supporting the support bars 250 to be coupled to the lower auxiliary holder 410, the lower auxiliary holder 410 is formed with a plurality of ball joint parts 411 to which the ball members of the lower support rods 420 can be rotatably coupled, respectively.

As described above, the lower auxiliary holder 410 may be formed with a plurality of fitting holes, in which the plurality of lower support rods 420 can be each interference-fitted, spaced apart at regular intervals along the circumferential direction of the lower auxiliary holder 410 or the vertical pole 110, instead of the ball joint parts.

On the other hand, as shown in FIG. 7 , the supporting unit may be installed on an upper side of the main holder 210 to support the support bar 250. Referring to FIG. 7 , the supporting unit includes an upper auxiliary holder 430 installed on an upper side of the main holder 210 to support the support bar 250, and an upper support rod 440.

The upper auxiliary holder 430 is installed to surround the vertical pole 110 on an upper side of the main holder 210, and is formed on one side with a ball joint part 431 capable of supporting an upper support rod 440 (which will be described later) so as to be rotatable by certain angles in the vertical and horizontal directions.

The upper support rod 440 is coupled at an upper end to the ball joint part 431 provided for the upper auxiliary holder 430 so as to be rotatable by certain angles in the vertical and horizontal directions, and is rotatably coupled at a lower end to a connecting bracket 270 coupled to one side of the support bar 250.

A spherical ball member is provided at the upper end of the upper support rod 440 coupled to the upper auxiliary holder 430 side, and the ball member is coupled to the ball joint part 431 so as to be rotatable to some extent in the vertical and horizontal directions in a state of being restrained in the ball joint part 431. Unlike the illustration, a hook portion of a hook structure may be formed on an end side of the upper support rod 440, and an engaging portion of a ring structure to which the hook portion can be engaged and fastened may be formed on the upper auxiliary holder 430.

The upper end of the upper support rod 440 is coupled to the upper auxiliary holder 430 on an upper side of the main holder 210 and the lower end of the upper support rod 440 is coupled to the support bar 250, so that the supporting unit can stably bear and support load acting on the support bar 250.

In addition, when a plurality of horizontal support units 200 are installed on the vertical pole 110 as shown in FIG. 8 , the supporting unit may further include a plurality of upper support rods 440. In order to allow the plurality of upper support rods 440 to be coupled to the support bars 250 for supporting the support bars 250 of the horizontal support units 200, the upper auxiliary holder 430 is formed with a plurality of ball joint parts 431 to which the ball members of the upper support rods 440 can be rotatably coupled, respectively. When the hook portion of the hook structure is formed on an end side of the upper support rod 440, the upper auxiliary holder 430 may be formed with engaging portions of a ring structure to be spaced apart at regular intervals along the circumferential direction of the upper auxiliary holder 430 or the vertical pole 110 so that the plurality of hook portions can be engaged and fastened thereto, respectively.

In addition, as shown in FIG. 9 , the supporting unit may be installed on each of upper and lower sides of the main holder 210 to support the support bar 250.

Referring to FIG. 9 , the supporting unit may include a lower auxiliary holder 410 and a lower support rod 420, which are installed on a lower side of the main holder 210 and support the support bar 250, and an upper auxiliary holder 430 and an upper support rod 440, which are installed on an upper side of the main holder 210 and support the support bar 250.

For the lower auxiliary holder 410 and the lower support rod 420 of FIG. 9 , the same configuration as that of the supporting unit described with reference to FIGS. 4 and 5 is applied, and for the upper auxiliary holder 430 and the upper support rod 440, the same configuration as that of the supporting unit described with reference to FIG. 7 is applied.

FIG. 10 shows another exemplary embodiment of the supporting unit. Referring to FIG. 10 , the supporting unit includes a lower auxiliary holder 410, a lower support rod 420, and a lower height adjusting part 450.

The lower auxiliary holder 410 is installed to surround the vertical pole 110 on a lower side of the main holder 210, and is installed to be movable up and down along the vertical pole 110. The lower auxiliary holder 410 is formed on one side with a ball joint part 411 capable of supporting the lower support rod 420 (which will be described later) so as to be rotatable by certain angles in the vertical and horizontal directions.

A spherical ball member is provided at a lower end of the lower support rod 420, and the ball member is coupled to the ball joint part 411 provided for the lower auxiliary holder 410 so as to be rotatable by certain angles in the vertical and horizontal directions. An upper end of the lower support rod 420 is rotatably coupled to a connecting bracket 270 coupled to one side of the support bar 250. As described above, the lower auxiliary holder 410 may be formed with a fitting hole capable of interference-fitting the lower support rod 420, instead of the ball joint part 411.

The lower height adjusting part 450 adjusts and fixes a position of the lower auxiliary holder 410, i.e., a height of the lower auxiliary holder 410 with respect to the vertical pole 110.

The lower height adjusting part 450 may include a lower screw portion 451 and a pair of lower rotary rings 452.

The lower screw portion 451 is formed within a certain range on the vertical pole 110 where the lower auxiliary holder 410 below the main holder 210 is located.

The lower rotary rings 452 are provided in pair so as to be each installed above and below the lower auxiliary holder 410. The lower rotary ring 452 has a passage hole through which the vertical pole 110 can pass, and an inner circumferential surface of the passage hole is formed with a coupling screw portion capable of screwing with the lower screw portion 451.

When the lower rotary ring 452 on an upper side of the lower auxiliary holder 410 is rotated in one direction about the vertical pole 110, the lower rotary ring 452 moves the lower auxiliary holder 410 down while descending along the vertical pole 110, and at this time, the lower support rod 420 whose lower end is coupled to the lower auxiliary holder 410 is pulled downward, thereby firmly supporting the support bar 250. Conversely, when the lower rotary ring 452 on a lower side of the lower auxiliary holder 410 is rotated in one direction about the vertical pole 110, the lower rotary ring 452 moves the lower auxiliary holder 410 up while ascending along the vertical pole 110, and at this time, the lower support rod 420 whose lower end is coupled to the lower auxiliary holder 410 is pushed upward, thereby firmly supporting the support bar 250. If necessary, any one of the lower rotary rings 452 on the upper and lower sides of the lower auxiliary holder 410 may be omitted.

FIG. 18 shows a supporting unit according to another exemplary embodiment of the present invention.

Referring to FIG. 18 , the supporting unit may include a lower support rod 510 and an upper support rope 520.

The lower support rod 510 supports the support bar 250 from below in order to prevent the support bar 250 from bending or sagging downward due to a weight of the awning or wind load. The lower support rod 510 is coupled, connected or supported at one end to or by the lower auxiliary holder 410 coupled to the vertical pole 110 on a lower side of the main holder 210, and is coupled, connected or supported at the other end to or by the support bar 250. For the lower support rod 510 according to the present exemplary embodiment, the same structure as the lower support rod 420 shown in FIGS. 4 to 6 can be applied.

The upper support rope 520 supports the support bar 250 from above in order to prevent the support bar 250 from bending or sagging downward due to a weight of the awning or wind load, and one end is introduced into the vertical pole via a passage hole provided for the vertical pole 110 on an upper side of the main holder 210 and is coupled to or supported by the vertical pole 110, and the other end is coupled, connected or supported to or by the support bar 250.

Unlike the illustration, the upper support rope 520 may be coupled, connected or supported at one end to or by the upper auxiliary holder 430 installed on the vertical pole 110, like the upper support rope 470 shown in FIGS. 13 to 15 , or may be wound on the upper winding part 320, like the first towline 310 shown in FIG. 17 .

FIGS. 19 and 20 show still another exemplary embodiment of the supporting unit.

Referring to FIGS. 19 and 20 , the supporting unit may include a plurality of individual support ropes 521, 522 and 523. For each of the individual support ropes 251, 252 and 253 according to the present exemplary embodiment, the same configuration as the upper support rope 520 described above with reference to FIG. 18 is applied.

The three horizontal support units 200 are installed adjacent vertically on the vertical pole 110, and the three individual support ropes 521, 522 and 523 are provided to support the three support bars 251, 252 and 253, respectively.

Each of the individual support ropes 521, 522 and 523 is connected at one end to the connecting bracket 270 provided on each of the support bars 251, 252 and 253 of the respective horizontal support units 200, and the other end thereof is fixed inside the vertical pole 110 through a passage hole provided for the vertical pole 110 on an upper side of the main holder 210.

The individual support ropes 521, 522 and 523 are installed such that tension acting on the individual support ropes 521, 522 and 523 increases as rotation angles of the support bars 251, 252 and 253 increase.

The first support bar 251 to the third support bar 253 are installed horizontally on the vertical pole 110 by the main holder 210, and the individual support ropes 521, 522 and 523 may be connected to the first support bar 251 to the third support bar 253, respectively. In an exemplary embodiment, the first support bar 251 is rotated by 90° from an initial position, the second support bar 252 is rotated by 180° from the initial position, and the third support bar 253 is rotated by 270° from the initial position. When the first support bar 251 to the third support bar 253 are rotated by different angles, as shown, the tension acting on the first individual support rope 521 to the third individual support rope 523 connected to the first support bar 251 to the third support bar 253 is different depending on the rotation angles.

As shown in FIG. 20 , the greatest tension acts on the longest portion where the third individual support rope 523 connected to the third support bar 253 rotated by the greatest angle is wound along the vertical pole 110, and the least tension acts on the shortest portion where the first individual support rope 521 connected to the first support bar 251 rotated by the smallest angle is wound along the vertical pole 110. When the user rotates the support bars 251, 252 and 253 by desired angles and fixes the support bars 251, 252, and 253 in a pulled state using additional strings, there is no need to additionally install a separate means for supporting the support bars 251, 252 and 253.

Lengths of the individual support ropes 521, 522 and 523 connected to the support bars 251, 252 and 253 may be configured to be the same in length from a fixed portion on the vertical pole side to a point connected to each of the support bars 251, 252 and 253 or may be configured to be different, in correspondence with differences in length wound on the vertical pole 110 according to the difference in rotation angles of the support bars 251, 252 and 253. In addition, the individual support ropes 521, 522 and 523 may be made of a non-elastic material, but may also be made to have elasticity by a stretchable material so as to automatically return the support bars 251, 252 and 253 to the initial state.

FIG. 21 shows a supporting unit according to another exemplary embodiment of the present invention.

Referring to FIG. 21 , the supporting unit may include a lower support rod 513 and an upper support rope 520. If necessary, the upper support rope 520 may be omitted, and the upper support rod 440 of FIGS. 7, 8, 9 and 12 may be applied.

A support bar 257 applied in the present exemplary embodiment is formed with an accommodation groove 258 that is drawn in from the bottom toward the top by a certain depth and is provided to enable the lower support rod 513 described later to be accommodated and pulled out. The support bar 257 may have a circular cross section, but may also have a square cross section so as to increase a size of the accommodation groove 258.

The lower support rod 513 is supported at one end by a lower auxiliary holder 410 coupled to the vertical pole 110 on a lower side of the main holder 210, and is rotatably coupled at the other end to the support bar 257. The lower support rod 513 has such a structure that it can be folded or unfolded at a center of its length, and is folded and accommodated in the accommodation groove 258 of the support bar 257 at normal times, and is rotated and unfolded from the support bar 257 to support the support bar 257 during use.

The first link member 511 is formed to be accommodated in the accommodation groove 258, and one end thereof is rotatably installed on an end side of the accommodation groove 258 facing toward a free end side of the support bar 257. One side of the first link member 511 is provided with an accommodation groove that is drawn inward, extends along the longitudinal direction and can accommodate the second link member 512. Preferably, the first link member 511 is kept introduced into the accommodation groove 258 of the support bar 257 at normal times, and can be pulled out and unfolded from the accommodation groove 258 of the support bar 257 only when the user tries to pull out the first link member by applying force.

The second link member 512 is formed to be introduced or pulled out with respect to the accommodation groove of the first link member 511. The second link member 512 is rotatably coupled at one end to the other end of the first link member 511 facing toward the main holder 210. When the second link member 512 is unfolded from the first link member 511, its end is seated, cradled or coupled on the lower auxiliary holder 410 side coupled to the vertical pole 110 side. The lower auxiliary holder 410 is formed with seating grooves, cradle grooves or coupling grooves spaced apart at regular intervals along the circumferential direction such that an end of the second link member 512 can be stably seated, cradled or coupled without slip.

The accommodation groove formed in the first link member 511 is formed in a direction opposite to the accommodation groove 258 formed in the support bar 258. Preferably, the second link member 512 is continuously kept introduced in the accommodation groove of the first link member 511 at normal times, and can be pulled out, rotated and unfolded from the first link member 511 only when the user tries to pull out the second link member by applying force.

As shown in FIG. 21 , although the lower support rod 513 may be installed in the lower part of the support bar 257 of the supporting unit, a structure where an upper support rod having the same structure as the lower support rod 513 is installed in an upper part of the support bar 257 can also be applied. In this case, the upper support rod is coupled at one end to the upper auxiliary holder installed on the vertical pole 110 on an upper side of the support bar 257, and is rotatably coupled at the other end to the support bar 257, thereby supporting the support bar 257.

In addition, although not shown in the drawings, the lower support rod 513 of the supporting unit may include a first link member rotatably coupled at one end to the vertical pole 110 on an upper or lower side of the support bar 257 and configured to be folded and unfolded with respect to the vertical pole 110, and a second link member rotatably coupled at one end to an end of the first link member and coupled at the other end to the support bar 257, and configured to be folded and unfolded with respect to the first link member. In this case, the lower support rod 513 has such a structure that it is rotatably coupled at one end to the vertical pole 110 and can be folded or unfolded with respect to the vertical pole 110 and is coupled at the other end to the support bar 257 to support the support bar 257.

Meanwhile, the supporting unit of the awning support device according to the present invention further includes a tension adjusting part connected to an upper support rope and configured to adjust the tension of the upper support rope, as shown in FIG. 22 .

The tension adjusting part pulls an upper support rope 520 to apply tension to the upper support rope 520 such that the support bar 250 can be supported through the support rope 520. To this end, the vertical pole 110 above the main holder 210 is formed with a passage hole through which the support rope 520 can pass.

Referring to FIG. 22 , the upper support rope 520 passes through the passage hole formed in the vertical pole 110 on an upper side of the main holder 110 and extends downward along the inside of the vertical pole 110 for a predetermined length. A lower end of the upper support rope 520 extends for a length sufficient to reach a position lower than the main holder 210.

An end of the upper support rope 520 is provided with a tension adjusting part for maintaining or releasing a tension-applied state of the upper support rope 520.

The tension adjusting part may include a locking hole 531 and a locking lever 532.

The locking hole 531 may include a sliding hole extending vertically in the vertical pole 110 below the main holder 210, and a plurality of adjusting holes extending horizontally from the sliding hole and spaced apart at regular intervals along a longitudinal direction of the sliding hole. The locking lever 532 is selectively introduced into any of the adjusting holes, and the locking lever 532 moved into the adjusting hole is blocked from moving up and down.

The locking lever 532 is installed inside the vertical pole 110 such that a part thereof is exposed to the outside of the vertical pole 110 through the locking hole 531. The locking lever 532 can apply tension to the support rope 520 when the user pulls down the locking lever in a state of gripping the same with a hand, and at this time, the support bar 250 can be supported upward firmly and stably by the tension applied to the support rope 520.

On the other hand, as shown in FIG. 23 , the tension adjusting part may be each provided on upper and lower sides of the horizontal support unit.

Referring to FIG. 23 , an upper support rope 541 and a lower support rope 542 are each connected to the support bar 250.

The upper support rope 541 passes through the vertical pole 110 through an upper passage hole formed at an upper part of the vertical pole 110 and extends downward inside the vertical pole 110.

The lower support rope 542 passes through the vertical pole 110 through a lower passage hole formed at a lower part of the vertical pole 110 and extends upward inside the vertical pole 110.

The vertical pole 110 on an upper side of the main holder 210 of the horizontal support unit is provided with an upper adjusting part connected to the lower support rope 542, and the vertical pole 110 on a lower side of the horizontal support unit is provided with a lower adjusting part connected to the upper support rope.

The upper adjusting part includes an upper locking hole 561 and an upper locking lever 562, and the lower adjusting part includes a lower locking hole 567 and a lower locking lever 568.

The lower locking hole 567 and the lower locking lever 568 have the same structure as the locking hole 531 and the locking lever 532 described above with reference to FIG. 22 , and the upper locking hole 561 and the upper locking lever 562 also have the same structure as the lower locking hole 567 and the lower locking lever 568, except that they are different from the lower locking hole 567 and the lower locking lever 568 in terms of installation positions.

When the user pulls the lower locking lever 568 downward while gripping the same with a hand, tension is applied to the upper support rope 541 so that the support bar 250 can be stably supported by the upper support rope 541 or bent upward to some extent, and when the upper locking lever 532 is pushed upward, tension is applied to the lower support rope 542 so that the support bar 250 can be bent downward to some extent by the lower support rope 542.

The upper support rope, the lower support rope, the first towline, and the second towline described above may be each connected with a spring member in the middle thereof, and when the upper support rope, the lower support rope, the first towline, and the second towline are loosened or damaged as they are used for a long time, the tension is preferably supplemented and reinforced using the elasticity of the spring member (tension spring) so as to maintain a tight state at all times.

FIG. 24 shows another exemplary embodiment of the supporting unit.

Referring to FIG. 24 , the supporting unit may include an upper auxiliary holder 430, an upper support rod 440, and a length adjusting part 610 installed on the upper support rod 440 and capable of adjusting a length of the upper support rod 440.

For the upper auxiliary holder 430, the same as the upper auxiliary holder 430 described with reference to FIG. 7 is applied.

The upper support rod 440 is divided into a first upper split rod 441 and a second upper split rod 442.

One end of the first upper split rod 441 is coupled to the upper auxiliary holder 430 and the other end is screwed to the length adjusting part 610 described later. The end of the first upper split rod 441 coupled to the length adjusting part 610 is formed with a first coupling screw portion 441A.

One end of the second upper split rod 442 is rotatably coupled to the connecting bracket 270 coupled to one side of the support bar 250, and the other end is screwed to the length adjusting part 610. The end of the second upper split rod 442 coupled to the length adjusting part 610 is formed with a second coupling screw portion 442A.

The length adjusting part 610 connects the first upper split rod 441 and the second upper split rod 442 between the first upper split rod 441 and the second upper split rod 442, is rotatably coupled to the ends of the first upper split rod 441 and the second upper split rod 442, respectively, and brings the first upper split rod 441 and the second upper split rod 442 close to or away from each other depending on a direction of rotation.

The length adjusting part 610 is provided on one side with a first fastening screw portion 611 screwed to the first coupling screw portion 441A of the first upper split rod 441, and is provided on the other side opposite to the first fastening screw portion with a second fastening screw portion 612 screwed to the second coupling screw portion 442A of the second upper split rod 442. The length adjusting part 610 extends for a certain length. An inside of the length adjusting part 610 has an open structure so that the first upper split rod 441 and the second upper split rod 442 can be introduced from different directions, respectively.

Accordingly, the support bar 250 connected to the second upper split rod 442 can be bent downward by a predetermined angle.

FIG. 25 shows another exemplary embodiment of the supporting unit.

Referring to FIG. 25 , the supporting unit may include a lower auxiliary holder 410, a lower support rod 420, and a length adjusting part 610 installed on the lower support rod 420 and capable of adjusting a length of the lower support rod 420.

For the lower auxiliary holder 410, the same as the lower auxiliary holder 410 described with reference to FIG. 4 is applied.

The lower support rod 420 is divided into a first lower split rod 421 and a second lower split rod 422.

One end of the first lower split rod 421 is coupled to the lower auxiliary holder 410 and the other end is screwed to the length adjusting part 610 described later. The end of the first lower split rod 421 coupled to the length adjusting part 610 is formed with a first coupling screw portion 421A.

The length adjusting part 610 connects the first lower split rod 421 and the second lower split rod 422 between the first lower split rod 421 and the second lower split rod 422, is rotatably coupled to the ends of the first lower split rod 421 and the second lower split rod 422, respectively, and brings the first lower split rod 421 and the second lower split rod 422 close to or away from each other, depending on a direction of rotation.

The length adjusting part 610 is provided on one side with a first fastening screw portion 611 screwed to the first coupling screw portion 441A of the first lower split rod 421, and is provided on the other side opposite to the first fastening screw portion 611 with a second fastening screw portion 612 screwed to the second coupling screw portion 442A of the second lower split rod 422. The length adjusting part 610 extends for a certain length. An inside of the length adjusting part 610 has an open structure so that the first lower split rod 421 and the second lower split rod 422 can be introduced from different directions, respectively. For the length adjusting part 610, a conventional turnbuckle structure may be applied.

When the length adjusting part 610 is rotated in a clockwise direction, the first lower split rod 421 and the second lower split rod 422 are brought closer to each other to reduce a length of the lower support rod 420. Accordingly, the support bar 250 connected to the second lower split rod 422 can be bent downward by a predetermined angle. Differently, when the length adjusting part 610 is rotated in a counterclockwise direction, the first lower split rod 421 and the second lower split rod 422 are spaced from each other to increase the length of the upper support rod 420. Accordingly, the support bar 250 connected to the second lower split rod 422 can be bent upward by a predetermined angle.

Although not shown in the drawings, for the supporting unit, a structure including the upper support rod 440, the lower support rod 420, and two length adjusting parts 610 described above with reference to FIGS. 24 and 25 may be applied.

FIG. 26 shows another exemplary embodiment of the supporting unit.

Referring to FIG. 26 , the supporting unit may include a lower auxiliary holder 410, a lower support rod 1420, and a buffering part 620. For the lower auxiliary holder 410 according to the present exemplary embodiment, the same as the lower auxiliary holder 410 shown in FIG. 4 may be applied.

The lower support rod 1420 is divided into a first split rod 1421 and a second split rod 1422.

One end of the first split rod 1421 is coupled to the lower auxiliary holder 410, and the other end is coupled to the buffering part 620 to be accessible thereto. The other end of the first split rod 1421 is formed with a first flange 1423 enlarged larger than a diameter of the first split rod 1421.

One end of the second split rod 1422 is rotatably coupled to the connecting bracket 270 coupled to one side of the support bar 250, and the other end is coupled to the buffering part 620 to be accessible thereto. The other end of the second split rod 1422 is formed with a second flange 1424 enlarged larger than a diameter of the second split rod 1422. The first flange 1423 and the second flange 1424 may have the same size.

The buffering part 620 may include a main body 621 that can accommodate the first flange 1423 of the first split rod 1421 in an inside on one side and accommodate the second flange 1424 of the second split rod 1422 in an inside on the other side opposite to the first flange 1423, and a buffer spring 622 that provides elastic force for causing the first flange 1423 and the second flange 1424 to be spaced apart from each other between the first flange 1423 and the second flange 1424 accommodated inside the main body 621. The main body 621 is installed to reciprocate or vibrate along the first split rod 1421 or the second split rod 1422.

When external force that bends the support bar 250 downward acts, compressive force acts on the lower support rod 1420 in a direction of compressing the lower support rod 1420. The compressive force is absorbed and relieved through the buffer spring 622 installed between the first split rod 1421 and the second split rod 1422, and accordingly, the lower support rod 1420 can be prevented from being broken or folded by the compressive force acting on the lower support rod 1420.

Although not shown in the drawings, an auxiliary spring for preventing the first flange 1423 from coming into contact with one end of the main body 621 may be further interposed between the first flange 1423 and one end of the main body 621. Similarly, an auxiliary spring for preventing the second flange 1424 from coming into contact with the other end of the main body 621 may be further interposed between the second flange 1424 and the other end of the main body 621.

When external force that bends the support bar 250 upward acts, tensile force to stretch the lower support rod 1420 in the longitudinal direction acts on the lower support rod 1420 for supporting the support bar 250. The tensile force is relieved to some extent as the first flange 1423 and the second flange 1424 move away from each other, and is completely absorbed and relieved through the auxiliary springs installed between the first flange 1423 and the second flange 1424. Accordingly, it is possible to prevent the lower support rod 1420 from being stretched, the end side of the lower support rod 1420 from being separated from the lower auxiliary holder 410, or the end side of the lower support rod 1420 from being separated from the support bar 250 or damaged due to the tensile force acting on the lower support rod 1420.

Meanwhile, FIG. 26 shows a structure in which the buffering part is installed only on the lower support rod. However, the supporting unit may further include an upper auxiliary holder coupled to an upper part of the main holder 210, an upper support rod for supporting the support bar 250 at the upper part of the support bar 250, and a buffering part for relieving tensile force or compressive force acting on the upper support rod. In this case, the upper auxiliary holder, the upper support rod, and the buffering part installed on the upper support rod may have the same structures as the lower auxiliary holder 410, the lower support rod 1420, and the buffering part 620 described in the present exemplary embodiment, except that they are different from the lower auxiliary holder 410, the lower support rod 1420, and the buffering part 620 in terms of installation directions.

FIG. 27 shows another exemplary embodiment of the supporting unit.

Referring to FIG. 27 , the supporting unit may include an upper auxiliary holder 430, a lower auxiliary holder 410, an upper support rope 470, a lower support rope 480, a first buffering part 630, and a second buffering part 640. For the upper auxiliary holder 430 and the lower auxiliary holder 410 according to the present exemplary embodiment, the same structures as the upper auxiliary holder 430 and the lower auxiliary holder 410 shown in FIG. are applied, respectively.

The upper support rope 470 is divided into a first upper split rope 471 and a second upper split rope 472.

One end of the first upper split rope 471 is connected to the connecting ring portion 437 of the upper auxiliary holder 430, and the other end is connected to one end of the first buffering part 630. Both ends of the first upper split rope 471 are formed with first upper fastening rings 471A that can be each engaged and fastened to one end of each of the connecting ring portion 437 and the first buffering part 630.

One end of the second upper split rope 472 is connected to the connecting bracket 270 provided on the support bar 250, and the other end is connected to the other end of the first buffering part 630. Both ends of the second upper split rope 472 are formed with second upper fastening rings 472A that can be each fastened to the other end of each of the connecting bracket 270 and the first buffering part 630.

The lower support rope 480 is divided into a first lower split rope 481 and a second lower split rope 482.

One end of the first lower split rope 481 is connected to the connecting ring portion 413 of the lower auxiliary holder 410, and the other end is connected to one end of the second buffering part 640. Both ends of the first lower split rope 481 are formed with first lower fastening rings 481A that can be each engaged and fastened to one end of each of the connecting ring portion 413 and the second buffering part 640.

One end of the second lower split rope 482 is connected to the connecting bracket 270 provided on the support bar 250, and the other end is connected to the other end of the second buffering part 640. Both ends of the second lower split rope 482 are formed with second lower fastening rings 482A that can be each engaged and fastened to the other end of each of the connecting bracket 270 and the second buffering part 640.

When tensile force acts on the upper support rope 470, i.e., the first upper split rope 471 and the second upper split rope 472 while the support bar 250 is being bent or folded downward, the first buffering part 630 absorbs and relieves the tensile force acting on the first upper split rope 471 and the second upper split rope 472. Both ends of the first buffering part 630 in the longitudinal direction are formed with fastening ring portions 631 to which the first upper fastening ring 471A and the second upper fastening ring 472A can be each engaged and fastened. For the first buffering part 630, a spring that increases in length when tensile force is applied in the longitudinal direction and returns to its original state when the tensile force is removed may be applied.

When tensile force acts on the lower support rope 480, i.e., the first lower split rope 481 and the second lower split rope 482 while the support bar 250 is being bent or folded upward, the second buffering part 640 absorbs and relieves the tensile force acting on the first lower split rope 481 and the second lower split rope 482. Both ends of the second buffering part 640 in the longitudinal direction are formed with fastening ring portions to which the first lower fastening ring 481A and the second lower fastening ring 482A can be each engaged and fastened. Like the first buffering part 630, for the second buffering part 640, a spring that increases in length when tensile force is applied in the longitudinal direction and returns to its original state when the tensile force is removed may be applied.

For each of the first buffering part 630 and the second buffering part 640, a general tension spring or a buffer spring such as ‘SAMINI (model name)’ available from ‘Misumi’ may be applied.

In the present exemplary embodiment, both the first buffering part 630 and the second buffering part 640 are applied. However, the second buffering part 640 may be omitted.

When the support bar 250 is bent upward or downward due to the external force acting on the support bar, the first buffering part 640 and the second buffering part 640 as described above absorb and relieve the tension acting on the upper support rope 470 and the lower support rope 480 to prevent the upper support rope 470 and the lower support rope 480 from being cut off or damaged.
